New(ish) LVP ILDA breakout board

[sbk]

Very interested Dave. I have three DMX output over my ethernet laser controller, this should be a nice way to use them

Depending on price, I might be interested as well.

Suggestion:
Since you have control over all the color-signals, maybe a scanfail could be implemented?

flipping the x and y by dmx could someone explain?

[taggalucci]

Inverting the image, either in the X or Y axis (or both).

Imagine 2 projectors both scanning downwards, flip the Y axis of one and you have one scanning down and the other scanning up. Both potentially from the same DAC.

Doing this by DMX means you'd have control of the axis flips from software like LivePRO instead of having to flip a DPDT switch on the back of the projector.

i understand what it does. its the dmx bit that confuses me.
is it just a switch on the back of the projector?

[taggalucci]

Just updated my explanation to include DMX

[Stuka]

Count me interested!!

are you asking what DMX is??? DMX is a serial protocol used for controlling lighting, moving heads, fog machines, strobes etc etc

if you are asking why you would want to the reason is simple, you can invert your X or Y while your projector is up in a truss or something during a show to create neat effects if your running satellites off of one DAC for example

Hows the progress going Dave?

I'd be up for 4 of these depending on price. Keep up the good work.

I would like to comment on the feature of controlling projection brightness through DMX:

Take care to only allow reduction of the projector's brightness through DMX. If you don't, you might mess up the Beam Attenuation Maps set in your DAC and even cause accidental laser emission by your lighting tech when your DAC isn't outputting a sensible signal.

If you scale the R/G/B brightness by a factor controlled by DMX (255 = full DAC brightness, 0 = off), you should have no problem. As long as the DMX brightness doesn't override the DAC's brightness signal.

Edit: You may even be able to scale X and Y in a similar manner through a set of DCA's, and allow arbitrary scaling of X and Y over DMX. In that case, make sure to clamp the value to a sensible lower boundary, because X and Y scaling of zero would result in a static beam.
